SOIL-PULVERIZING IMPLEMENT.

Application led May 31, 1921,v Serial My invention relates to improvements in soil pulverizing implements and more particularly to that class or type of soil or earth working implements commonly known as packers and mulchers77 in which front and rear gangs of spiral extending packer discsare employed, the ends of the axles of the front and rear gangs being mounted in and connected by oscillatory gang bearing or yoke members, pivotally or 'flexibly connected to the' main implement or draft frame and commonly known as double gang-pulverizers. In this type ofimplement it is desirable that means'be provided whereby certain pre-determined pulverizer or packer discs may be removed from the transversely extending axle shaft and the remaining packer orginiplementV discs be secured in relatively fixed spaced relation to' provide suitable spaces to receive the rows of growing crops whereby the soil between such rows may be cultivated or packed and Vmulched. Heretofore this has been accomplished through what is known as quick detachable discs much as disclosed and claimed in Dunham Patent No. 1,237,182, of August 14, 1917.

The primary object of this invention is to provide a generally improved implement of the class mentioned ofexceedingly efficient and simple construction, and to eliminate the need of such split or quick detachable discs through the medium of improved oscillatory gang bearing or yoke members attached to and mounted upon the 'implement or draft frame and to the ends of the gang axle shafts whereby the same may be readily attached to ordetached from such draft frame and axle: shafts without disassembling or disconnecting the main or draft frame from the oscillatory gang bearing yoke members, so that ordinary one-piece pulverizer discs may be employed and such discs may be readily placed upon or detached from such axle bearing shafts, as well as placed in any desired manner by simply detaching the gang bearing members from the ends of ,the draft orv implement frame, as will herein.- after more fully appear. v A further and very important object is the provision of improved means of mounting and detachably connecting the oscillatory gang bearing yoke members to the ends of the main implement or draft frame through the medium of improved two-part No. ll,7 3.,654-.. Renewed June 25,1924.

or split bearing heads,` the gang bearing yoke members being provided with inwardly extending bearing members yorlugs extendmg into said split bearing heads of the draft frame. s A still `further and very impor-tant object is the provision `of improved splitvor twopart bearing heads adapted to detachably receive and contain the ends of the gang axle shafts and axle shaft bear-ing'boxes, whereby said shafts may be readilyremoved without detaching the oscillatory gang bearing yoke members from the ends ofthe draft or` main implement frame. i `r l. i `With the above mentioned and other ends in view, the invention consists in the novelA construction, arrangement, and combination. of parts, hereinafter' described, illustrated insomeof its embodiments in the accompanying drawings, and particularly pointed outin the appended claims. i

The improved soil pulverizer or tillage implementcomprises a main implement or draft frame consisting, in the present instance of transverse bars 1, provided at their ends with depending bearing members 2, the latter being, in the present instance, in the specific form of bearing brackets terminating at their lower ends in bearing heads 2, provided with bearing openings 2b. The implement or draft frame is adapted to be drawn by means of a centrally located draft bar or tongue 3.

The improved implement preferably comprises front and rear gangs of soil pulverizer discs 4, and 5, respectively, the front pulverizer or packer discs 4, being preferably larger in diameter than the rear disc 5,

' and as a means of removably and ajustably mounting said discs 4, and 5, and providing means whereby an oscillatory or rocking movement will be permitted to said front and rear gangs of discs to conform to or meet the varying contour of the surface being cultivated, front and rear axle shafts 6, and 7, respectively, are provided, the discs 4, and 5, being provided with suitable openings forming bearings and being loosely mounted on the shafts 6, and 7.

As a means of so pivotally or flexibly connecting the axles of the front and rear disc gangs to thebearing heads 2, of the depending bearing members or brackets of the main or draft frame that the greatest weight and pulling stresses will be transmitted to the front disc gang in view of their taking the initial and more difficult part of the pulverizing operation, oscillatory gang bearing bars or yoke members are arranged f between and connected to the ends of the shafts 6, and 7. The oscillatory yoke members or bars may be either in the specific form of trailer gang yokes 8, as shown'in Figs. 1, 2, 8, 4, 5, 10, and 11 of the drawings, or in the form of counterbalanced yokes 8a, as shown in Figs. 13 and 14 of the drawings in which the pivoted connections or points of oscillation between the members 8, and the heads 2, of the brackets 2, are

between vertical planes passing through the axes of the shafts supporting the respective front and rear gangs but preferably closer to the front shaft 6, than the rear shaft 7, as shown.

As a means of enabling the discs in the respective front and rear gangs to be removed from or adjusted on the rear axle shaft 7, and front axle shaft 6, without dismantling or disassembling the main or draft frame so that if desired certain of the discs or packer wheels may be removed from or rearranged on the shafts 6, and 7, to form spaces or passes for receiving rows of growing crops, the gang bearing or yoke members 8, and 8a, are arranged to be inserted on or removed from the outer ends of the shafts 6, and 7, and the bearing heads 2a, of the brackets 2, by providing the ends and intermediate portions of the gang bearing members 8, and 8a, respectively, with bearing portions or heads adapted to be inserted in the openings 2", of the heads 2a.

In the form of implement shown in Figs. 1, to 12, inclusive of the drawings, the trailer yokes 8, are provided at their rear ends with bearing heads 8,having bearing openings 8, to removably receive and contain the ends of the .rear axle shaft 7, and the front ends of the yokes 8, are provided with inwardly extending pivot bearing portions 8", extending into the bearing heads 2", of the draft frame, said bearing portions 8d, in the present instance, being in the specific form of axle shaft bearing boxes adapted to also receive vand contain the ends of the front axle shaft 6.

As a means of quickly attaching the combined axle shaft and pivot bearing portions 8", of the trailer yokes 8, to the bearing heads of the draft frame without disassembling the latter, the bearing heads comprise what may be termed split or two-part bearing members comprising the relatively fixed bearing heads 2, and the detachable or removable bearing member 2c (see Figs. 7 andk 8), the parts 2a, and 2, comprised in the two-part bearings being provided on their inner sides with a circumferential groove 2, to removably receive and contain an annular circumferentially extending bearing flange Se, on the axle shaft bearing boxes 8d.

The removable bearing member 2c, may be readily attached to or detached from the relatively fixed member 2a, by means of the attaching elements or bolts 2e, and it will be obvious that when it is desired to detach or rearrange the discs 4, and 5, on the shafts 6, and 7, the axle bearing portions or boxes 8d, may be readily removed by simply removing one of the fastening elements or bolts 2e, at one side or the other thereby dropping down the movable member 2, sufficiently to enable the heads 8b', and yokes 8, to be moved laterally from the ends of the axles 6, and 7. If

desired, the outer portions of theibearing heads 8b', andi'l,- be' providedvvith qui/ck detachable" dust excluding caps 8f. In this form of soil pulverizer implement the rear ends' ofjthe' trailer y-okes"4 8, may be connected and:V held' a certain distance apart byv means of pivctally connected' upwardly extending supports* 9,. connectedl at' their upper' ends an'd'adapted-to support a rear gang 'crossbarl'O, the latter being provided WithI a seat supporting; spring l1, carrying a seat l2, The' rear' end i movement ofthe cross-bar 10, and seatsuppforting spring Il, may be limit'- ed in any suitable and convenient manner, as Ifor eXarnple,-a flexible connection I3', such' as a chain or the like ezlrtendingbetween the' yupper end ,of the seat supporting spring. 113 and'tlie transverse draftframel l". The' lower ends of the support 9, are pivotfally' eonn'ectedto upwardly extending lugs 8F, at'thej'rear yends ofthe traileryokes 8,.by means- .fpivot elements orb'earings 961, and it Will'be obvious'in view ofthe relative loca'- tion o'f the connections 9", and 13, With respect totlife eonneetin's 8, with the bearing heads4 ofthe main frame that-the oscillations of the rear gang of discs 5,\Will be minimized at the seat 12.' g

Thev coui'iterbalanced yokes 8a, shown in Figi-1.713, 14`, an'd 15j of the drawings, may be securedto the bearing heads 2a, of the draft frame' suitable'A and convenientu inan-v ner, as for eXan'iple`,-'by meansof inwardly extending bearing members yor lugs 8", eX- tending inwardly into' the' openings 2b, and, if'- desired, the. bearing members 8b, 'may be s'e'curedin the'l bearing heads 2a', by means of retainingl bolts 14", passing through centralr openings! in thev lugs or heads 8h, With bearing Washers 14a",- to" engage With inner sides ofthe bearingheads" 2, tlie outer ends ofth'e'blts being provided with nuts 14h'.-

As ai mean'sof enabling,theyok'e's`- 8, to* be quickly attached to or detached' fromv the ends of the axle shafts 6, and 7, for removing or rearranging or adjusting any of the discs of the front and rear disc gangs Without detacliing; the pivoted portions of the yokes from the bearing heads of the draft frame, the ends of the yokes 8a, vcan be made in split or two-part bearing heads consisting, in the present instance, of a relatively fixed bearing portion 8i, and a relatively movableA bearing member 8j. f

In the present instance,-the movable members 8j, are pivotally or hingedly connected to one side of the block 8i, by means of pivot bolts 8k, and the free ends of the movable members 8j, may be secured in their fixed or assembled positions by meansof securing bolts 8.

The members of the split or two-part bearings are preferably provided on their inner sideswith circumferentially extending bearing grooves 8m, adapted to receive acorre- Having thus described some-ofthe embodiments" o'lff my invention,` Wha-t` I claiml and desire to secure'` by Letters Patent,,is,l
